Inflammatory myofibroblastic tumor (IMT) infrequently involves the sigmoid colon, and has not previously been described in an infant sigmoid colon. An inflammatory myofibroblastic tumor arose from the sigmoid colon of an 11-month-old boy, confirmed by anaplastic lymphoma kinase (ALK), smooth muscle actin (SMA) and desmin immunohistochemical staining. The patient recovered well after complete resection of the tumor. Sigmoid IMT can occur in infancy. This eighth case is the youngest so far. The child did well after surgical resection.
炎性肌纤维母细胞瘤（IMT）很少累及乙状结肠，此前尚无婴儿乙状结肠发生IMT的报道。一名11个月大男童的乙状结肠发生了炎性肌纤维母细胞瘤，经间变性淋巴瘤激酶（ALK）、平滑肌肌动蛋白（SMA）和结蛋白免疫组化染色得以确诊。肿瘤完整切除后，患儿恢复良好。乙状结肠IMT可发生于婴儿期。这是第八例，也是迄今为止最年幼的病例。该患儿手术切除后情况良好。
